44 has depending ends such as 45.

. fi tainers I8 and screws I9,'see Fig. 5. Said platen member is removably or hingedly mounted upon the casing in any suitable manner such as that indicated in the drawings by way of illustration. Upright supports 20 .are fastened by bolts 2| to the casing or side walls I2. A U-shaped frame extends around three sides of platen frame I 6 and includes side members 22 pivotally connected by bolts 23 to said supports 20 and has a front member 24, see Figs. and 6, carrying a handle 25 and spring latch 26 for engaging the catch 21 mounted on front wall III. The platen member has angle plates 28 centrally mounted at each end of plate frame I6 and connected to the side'mem-y bers 22 of the U-shaped frame by means of bolts 29. Said side members 22 extend beyond said back wall I I and coil springs 30 are attached at one end to eyelets 3| on said extensions of side members 22 and at the other end to eyelets 32 on the back wall I I. As a result, the platen member is normally held by the coil springs 30 in a raised position as indicated by the dotted lines in Fig. 5. The platen member may be lowered by pressing on the handle 25 and moving spring latch 26 into engagement with catch 21, the platen frame I6 being rotatably mounted upon the U- shaped frame so that the platen member and/or transparent member thereof may locate itself upon the top edges of the casing walls or against the copy on the receiving assembly.

-The copy receiving assembly comprises generally a pair of copy supports and one or more vlinkages operatively connected'to said supports and permitting relative movement thereof. The

cops7 supports 35 and 36 :are preferably covered With a rubber mat 31 also extending over the spacing between the supports 35 and 36 and for supporting the back of a boek to be copied. Such a book 38 may have covers 39 and 45, although lthe copyhoder is not limited to use with any particular form of copy such as a bound volume. The linkage for the copy supports is preferably a parallelogram linkage. Specifically, a cross bar 4I has depending ends 42 and 43 and a cross bar Straps 46 each have curved ends 41 provided with slots 48 .for engaging headed screws 49 on each of the cross bars 4I and 44. As best shown in Fig. 2, said straps 46 may extend over the book covers 39 and 40 to hold them on the respective copy supports 35 and 36. Two pairs of links 50 and 5|, 52 and 53 are pivotally connected at opposite ends to the depending ends of the cross bars 4I and 44. Link 50 is pivotally connected at one end to depending end 42 of cross bar 4I by a bolt 54 and at the other end to the depending end 45 of cross bar 44 by a bolt 55. Link 5I is pivotally connected at one .end to depending end 42 by a bolt 56 and at the other end to depending end 45 by bolt 51, links 52 and 53 being pivotally connected in `a similar manner to the opposite depending ends of said cross bars 4Ir and 44. l Since the pivotal connections of the links to the depending ends of the cross bars 4Ik and 44 are vertically spaced, a parallelogram linkage is formed for supporting the copy supports 35 and 36. Preferably as shown, there is such a parallelogram linkage adjacent each offront wall I0 and back wall YII for a stronger arrangement of the copy receiving assembly. f

A transverse rod 58 extends through the centers of links 50 and 52 and carries on each end .a roller 59 for rolling engagement with the angle irons I4 forming the guideways in thel'walls I|J and II. A second transverse rod 50 also has rollers 5I on each end thereof for engaging the angle irons I4 of the guide-ways I3 and extend-s through the centers of links 5I and 53. When the copy receiving assembly is supported by said rods 58 and 6U, ,the copy supports 35 and 36 are maintained in parallel relation to each other during their relative movement and so that the copy thereon or rubberfmat 31 is supported in a substantially horizontal plane.

A pulley 62 is fastened to link 5I and a pulley 63 is fastened to link 53 by a pair of screws 64, see Figs. 2 and 4. The transverse rod 60 is free to rotate within said links 5I and 53 and within said pulleys 52 and 53. The peripheries of said pulleys 62 and 63 lare recessed in a known manner to receive one or more turns of a rope mem-ber next to be described.

In the illustrated embodiment .the rope member B5 is fastened at one end in the recessed periphery of a pulley 65 mounted upon a rod 61 journaled at each end in the walls I 5 and I I. Said rope member 65 extends from said pulley 66, is wrapped at least once around the periphery of pulley 53, then extends to theleft-hand side wall i2, being fastened thereto by clamps 68 Whereupon said rope member 65 encircles pulley B2 and extends to and is fastened to a pulley 69 upon the other end of rod 61 adjacent the front wall I 0. The arrangement of said rope member 65 isjbest illustrated in Fig. 1 land it is obvious that rotation of rod 51 Will raise or lowerthe copy receiving assembly comprising the transverse rods 58 and 60, the parallelogram linkages and the copy supports 35 and 35. For instance,.said rope member 65 may support the copy receiving assembly in the position shown in full lines in Fig. 4 for supporting a relatively thick book or volume between copy supports 35 and 36 and the platen member. Winding of the rope member onto pulleys 66 and 65 will shorten the stretches between pu'ley 56 and clamp 68 and between pulley 69 and the other` clamp 68 so that the copy receiving assembly will be elevated to a position such as shown inFig. 2 for holding an average book against the transparent member I1 of the platen means. Finally, the copy receiving assembly may Ibe elevated as shown in dotted lines in Fig. 4 for holding a single sheet or document in contact with the transparent member I1.

An adjustable means is provided for manual rotation of said rod 61 and is preferably nonreversible as shown. A bracket l5 is fastened to one c-f side walls I2 by machine screws 1I and a shaft 12 is journaled in said bracket and extends through side wall I2 to receive a knob 13. A worm 14 is mounted upon said shaft 12 between the side walls of bracket 10 and meshes with a worm wheel 15 which is fastened to rod 61 by a set screw 16. Asa result, rotation of knob 13 will cause rotation of the rod $1 in a corresponding directionlso that the pulleys IIi and 69 are rotated either to wind or unwind the rope member 65. The worm V14 and worm vwheel 15 are arranged in a well known *manner and 3B will not alter the Vsetting of rodi`61 by knob 1s. n y., V'Ifhe outstanding advantage of; theuse of; one or more rope members to support thecopy'; re-

frs

ceiving assemblyV according to the invention is that said rope member may be shortened or Iengthened to vary the posi-tion of the assembly and frictionally engagesthe pulleys 62 and 6'31w-ll1icl-1 arey attached to the parallelogram linkages so that the copy supports 35 and 3S are frictions/ily heldin.` such position. in other Words, when thel platen: member is open the copy' re.- ceivi-ng assembly remain-s substantially in the same position and the copy supports 35 and B dotnet move relatively toeach other even though there may be considerably more, thanI half of the weight of the copy or book upon one of said' supports. rl'-'hus, it the` top. pages of abound volume are in` the same plane by reason of the copy receiving assembly having been pressed against the platen member when closed, thel top pages.l of' the book' or volume will remain in the same` position even after the platen member is opened and even if the Weight or the book being copied is quite unevenly` divided between the supports 35. and 316:. The: slight inherent resiliency in the material ot the rope member $5 permits the` elimination. ofl all springs` from the COPY- holder.

In, practice, the; bound volume may have its covers: attachedV to copy supports` and 35i by straps a6, the platen member is closed against theaction of coil springs 3i) and held in such closed position by the spring latch 2li.- engaging u .the catch 21:.` Knob lf3` is thenA rotated, to;` raise the entire.` copy receiving assembly until the open pages; of the bookV are pressed against. the glass platen. rIhe platenmember may be opened and the pages of the book. turned to. another place and closing of the platen member will press on the; top pages oi the beek` halves to readjust` the relative positions; of the c opy supports and. 3S; Such readjlustment is permitted by the frictional engagement between, the rope member S5- and the pulleys 62 and BS. Also, the copy receiving assembly may be4 elevated so` asl to. press a` single sheet or document against the transparent member. Il of the platen member and the, copy supports 35. and 35 will be moved into the same plane and held in that position by the irictional engagement between the rope member S5 and the pulleys. 62. and 63.

Consequently, the frictional engagement between the supporting rope member and said pulleys t2` and 83. either holds the platen members 35 and 36. in any set position or permits their readjustment by reason of different thicknesses of copy between the respective copy supports 35 and 36 and the platen member. Furthermore, said rope member provides a very simple and effective manner of' adjusting the spacing between said copy supports 35 and 36 and the transparent member I1 ofthe platen member so that different thicknesses of copy may be held at against said transparent member Il'.

As indicated herein, the eopyholder according to the. invention may be varied, such as by providing a single parallelogram linkage to support the copy supports 35 and' 36. Other modifications of the invention are also possible so that the, present disclosure is to be construed' in an illustrative sense, the scope of the invention being defined by the claims which follow.
